Description

Technical Field

[0001] The present disclosure relates to the technical field of automobile seat production, and in particular to a fixing buckle, an automobile leather cover and an automobile seat. Background Art

[0002] In the modern automotive industry, car seats, as a crucial component of the vehicle interior, not only support the weight of passengers and provide a comfortable ride, but also directly impact the vehicle's safety performance and interior aesthetics. To enhance seat comfort and durability, automakers commonly use leather as a surface covering. This not only enhances the seat's texture but also makes it easier to clean and maintain.

[0003] Car holsters are typically designed to provide a secure connection to the seat, ensuring they won't shift or fall off during extended use. A common method involves attaching hooks to one side of the holster. These hooks engage support rods within the seat's internal structure, securing and supporting the holster. As part of the seat frame, the support rods possess sufficient strength and stability to resist deformation and damage during daily use, ensuring a secure holster installation.

[0004] However, in practice, this fixing method has also exposed certain problems. When the driver or passenger sits in the car seat, the seat bottom is subjected to pressure from the human body. This pressure is transmitted through the leather cover to the fixing buckle, causing the buckle to be squeezed downward. For some fixing buckles with suboptimal designs, this continuous squeezing force may weaken the connection between the buckle and the support rod. Especially after long-term repeated loads, the connection may loosen, increasing the risk of the car cover shifting. Utility Model Content

[0005] The purpose of the present invention is to overcome the deficiencies in the prior art and to provide a fixing buckle, a car leather cover and a car seat that can be buckled with a support rod of an internal structure of a seat without loosening and causing displacement of the car leather cover.

[0006] The purpose of this disclosure is achieved through the following technical solutions:

[0007] A fixed buckle for connecting a support rod of a car seat, comprising a buckle fabric, a buckle shell and a buckle assembly, wherein the buckle fabric is used to connect to a leather case body, and the buckle shell is connected to the buckle fabric; the buckle assembly comprises a first buckle component and a second buckle component, wherein the first buckle component comprises a first buckle tooth and a third buckle tooth arranged oppositely, and the second buckle component comprises a second buckle tooth and a fourth buckle tooth arranged oppositely, wherein the first buckle tooth, the second buckle tooth, the third buckle tooth and the fourth buckle tooth are all connected to the inner wall of the buckle groove, and the first buckle tooth, the second buckle tooth, the third buckle tooth and the fourth buckle tooth are all connected to the inner wall of the buckle groove, and the first buckle tooth, the second buckle tooth and the third buckle tooth are ... The ends of the third buckle tooth and the fourth buckle tooth are inclined toward the bottom of the buckle shell, so that the first buckle tooth and the extension line of the third buckle tooth form a first preset angle, and the second buckle tooth and the extension line of the fourth buckle tooth form a second preset angle, there is a first horizontal gap between the first buckle tooth and the third buckle tooth, and a second horizontal gap between the second buckle tooth and the fourth buckle tooth, so that the support rod passes through the first horizontal gap and the second horizontal gap in sequence and then is connected to the buckle shell, and the support rod contacts the second buckle component and the buckle shell respectively.

[0008] In one embodiment, the first preset angle is 40°-50°.

[0009] In one embodiment, the second preset angle is 40°-50°.

[0010] In one embodiment, the distance range of the first horizontal gap is 9-11 mm.

[0011] In one embodiment, the distance range of the second horizontal gap is 9-11 mm.

[0012] In one embodiment, the first horizontal gap is equal to the second horizontal gap.

[0013] In one embodiment, the buckle fabric has an adhesive layer, and the adhesive layer is arranged on a side of the buckle fabric facing away from the buckle shell.

[0014] In one embodiment, the opening distance of the hook slot is 3±0.3 cm.

[0015] In one embodiment, the first thread is a silicone thread.

[0016] In one embodiment, the second thread is a silicone thread.

[0017] In one embodiment, the third thread is a silicone thread.

[0018] In one embodiment, the fourth thread is a silicone thread.

[0019] A car leather case comprises a leather case body and the fixing buckle described in any one of the above embodiments, wherein the fixing buckle is connected to the leather case body.

[0020] A car seat comprises a seat foam, a support rod and the car leather cover described in the above embodiment, wherein the seat foam partially wraps the support rod, and a partial structure of the support rod is located in a gap of the seat foam, and the car leather cover is buckled with the partial structure of the support rod.

[0021] Compared with the prior art, the present disclosure has at least the following advantages:

[0022] The above-mentioned fixed hook comprises a first buckle component and a second buckle component, namely, a first buckle tooth, a second buckle tooth, a third buckle tooth and a fourth buckle tooth. The first buckle tooth, the second buckle tooth, the third buckle tooth and the fourth buckle tooth are all inclined toward the bottom of the buckle shell, thereby guiding the support rod of the car seat to be buckled. Since the extension line of the first buckle tooth and the third buckle tooth forms a first preset angle, and the extension line of the second buckle tooth and the fourth buckle tooth forms a second preset angle, the connection strength between the fixed hook and the support rod is enhanced, so that the support rod is less likely to fall out after passing through the first horizontal gap and the second horizontal gap in sequence, and the support rod contacts the second buckle component and the buckle shell respectively. Even if the bottom surface of the seat is subjected to pressure from the human body, it is less likely that the connection part will loosen and cause the car leather cover to shift. The arrangement of the first buckle component and the second buckle component can further enhance the connection strength between the fixed hook and the support rod, so that the support rod is less likely to fall out from the buckle shell.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0032] In order to better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure is further described in detail below with reference to specific embodiments:

[0033] See also Figure 1 and Figure 2 , which is a fixed buckle 10 of an embodiment of the present invention, used to connect the support rod of a car seat, including a buckle fabric 100, a buckle shell 200 and a buckle assembly 300.

[0034] The buckle fabric 100 is used to be connected to the leather case body, specifically by bonding or sewing; the buckle shell 200 is connected to the buckle fabric 100, and the buckle shell 200 has a buckle groove 201, which is used to accommodate part of the support rod; the buckle assembly 300 includes a first buckle component 310 and a second buckle component 320, the first buckle component 310 includes a first buckle tooth 311 and a third buckle tooth 312 arranged oppositely, the second buckle component 320 includes a second buckle tooth 321 and a fourth buckle tooth 322 arranged oppositely, the first buckle tooth 311, the second buckle tooth 321, the third buckle tooth 312 and the fourth buckle tooth 322 are connected to the inner wall of the buckle groove 201, and the first buckle tooth 311 and the second buckle tooth 321 are connected to the third buckle tooth 312 and The fourth latching teeth 322 are arranged opposite each other. The ends of the first latching teeth 311, the second latching teeth 321, the third latching teeth 312, and the fourth latching teeth 322 are tilted toward the bottom of the hook housing 200, so that the extension lines of the first latching teeth 311 and the third latching teeth 312 form a first predetermined angle, and the extension lines of the second latching teeth 321 and the fourth latching teeth 322 form a second predetermined angle. A first horizontal gap D1 exists between the first latching teeth 311 and the third latching teeth 312, and a second horizontal gap D2 exists between the second latching teeth 321 and the fourth latching teeth 322. This allows the support rod to sequentially pass through the first and second horizontal gaps before connecting to the hook housing 200, and the support rod contacts the second latching member 320 and the hook housing 200, respectively. In another embodiment, the hook groove 201 is a U-shaped hook groove.

[0035] In this embodiment, the fixed hook 10 has a first buckle component 310 and a second buckle component 320, that is, a first buckle tooth 311, a second buckle tooth 321, a third buckle tooth 312 and a fourth buckle tooth 322. The first buckle tooth 311, the second buckle tooth 321, the third buckle tooth 312 and the fourth buckle tooth 322 are all inclined toward the bottom of the hook shell 200, thereby guiding the support rod of the car seat to be buckled. Since the extension line of the first buckle tooth 311 and the third buckle tooth 312 forms a first preset angle, and the extension line of the second buckle tooth 321 and the fourth buckle tooth 322 forms a The second preset angle enhances the connection strength between the fixed hook 10 and the support rod, making it less likely for the support rod to fall out after passing through the first horizontal gap and the second horizontal gap in sequence, and the support rod contacts the second buckle component 320 and the buckle shell 200 respectively. Even if the bottom surface of the seat is subjected to pressure from the human body, it is less likely for the car leather cover to shift due to loosening of the connection part. The setting of the first buckle component 310 and the second buckle component 320 can further enhance the connection strength between the fixed hook 10 and the support rod, making it less likely for the support rod to fall out from the buckle shell 200.

[0036] In one embodiment, the first preset angle is 40°-50°.

[0037] In one embodiment, the second preset angle is 40°-50°.

[0038] It can be understood that since the first buckle tooth 311 and the third buckle tooth 312 are arranged on the corresponding inner wall of the buckle shell 200 and are both arranged towards the bottom of the buckle shell 200, the first buckle component 310 formed by the first buckle tooth 311 and the third buckle tooth 312 has the function of guiding the support rod of the car seat, and a first preset angle is formed between the first buckle tooth 311 and the third buckle tooth 312, so that the support rod is not easy to detach from the first buckle component 310 after passing through the first horizontal gap. In addition, the second buckle tooth 321 and the fourth buckle tooth 322 are arranged on the corresponding inner wall of the buckle shell 200 and are both arranged towards the bottom of the buckle shell 200, so that the second buckle tooth 321 and the fourth buckle tooth 322 formed by the second buckle tooth 321 and the fourth buckle tooth 322 The latch member 320 serves to guide the support rod, and a second predetermined angle is formed between the second latching teeth 321 and the fourth latching teeth 322. This makes it more difficult for the support rod to disengage after being sequentially latched to the hook housing 200 via the first latch member 310 and the second latch member 320. Under the action of the second latch member 320, the support rod simultaneously contacts the second latch member 320 and the hook housing 200, preventing the connection from loosening. This further reduces the likelihood of displacement of the car cover due to the combined action of the second latch member 320. Even when the driver or passenger sits on the car seat and the seat bottom is subjected to human pressure, the support rod remains in contact with the second latch member 320 and the hook housing 200. In this embodiment, the first predetermined angle is 50°; in another embodiment, the second predetermined angle is 50°, making it even more difficult for the support rod to disengage due to the combined action of the first latch member 310 and the second latch member 320.

[0039] like Figure 1 As shown, in one embodiment, the distance range D1 of the first horizontal gap is 9-11 mm.

[0040] like Figure 1 As shown, in one embodiment, the distance range D2 of the second horizontal gap is 9-11 mm.

[0041] It can be understood that the support rod of the car seat has a certain cross-sectional diameter length, and the support rod is fastened to the hook shell 200 through the first snap component 310 and the second snap component 320. Specifically, the support rod passes through the first horizontal gap formed between the first snap tooth 311 and the third snap tooth 312 and the second horizontal gap formed between the second snap tooth 321 and the fourth snap tooth 322 in sequence to be fastened to the hook shell 200. During this period, the first snap component 310 and the second snap component 320 both have a guiding function, making it easy to fasten the support rod. Under the action of the above-mentioned first preset angle and the second preset angle, the fastened support rod is less likely to disengage. In this embodiment, the horizontal distance of the first horizontal gap and / or the second horizontal gap is 10 mm, and the cross-sectional diameter length of the support rod is 14 mm.

[0042] In another embodiment, the first horizontal gap D1 is equal to the second horizontal gap D2. In this way, the force required for the support rod of the car seat to pass through the first horizontal gap and the second horizontal gap in sequence is equal, thereby balancing the difficulty of passing through the first horizontal gap and the difficulty of passing through the second horizontal gap, so that the support rod can be located at the bottom of the buckle groove 201, which is easy to make into a car seat.

[0043] like Figure 3 As shown, in one embodiment, the buckle fabric 100 has an adhesive layer 101, which is disposed on a side of the buckle fabric 100 facing away from the buckle housing 200. It is understood that the fixed buckle 10 is generally connected to a car holster, specifically, bonded to the car holster body via the adhesive layer 101. During the processing of the car holster, the adhesive layer 101 is melted to form an adhesive, which is then bonded to the car holster body. This allows the adhesive to better adhere to the car holster body after cooling.

[0044] In another embodiment, if Figure 4 As shown, the buckle fabric 100 has a sewing area 102, which is arranged away from the opening of the buckle shell 200, so that the fixed buckle 10 is connected to the car leather cover body through a sewing operation. Specifically, a sewing operation is performed on the sewing area 102 through a sewing device, so that the fixed buckle 10 is connected to the car leather cover body.

[0045] like Figure 1 As shown, in one embodiment, the opening distance D3 of the hook groove 201 is 3±0.3 cm. In this embodiment, the opening distance D3 of the hook groove 201 is 3 cm.

[0046] In one embodiment, the first thread 311 is a silicone thread; and / or,

[0047] The second fastener 321 is a silicone fastener; and / or,

[0048] The third fastener 312 is a silicone fastener; and / or,

[0049] The fourth thread 322 is a silicone thread.

[0050] It can be understood that when the first latching teeth 311, the second latching teeth 321, the third latching teeth 312 and the fourth latching teeth 322 are all silicone latching teeth, due to the good flexibility of silicone, when the support rod of the car seat passes through the first horizontal gap and the second horizontal gap in sequence, the support rod contacts the first latching teeth 311, the second latching teeth 321, the third latching teeth 312 and the fourth latching teeth 322 respectively, so that the first latching teeth 311, the second latching teeth 321, the third latching teeth 312 and the fourth latching teeth 322 are easily deformed when the support rod passes through, thereby better guiding the support rod to be fastened with the U-shaped hook shell, thereby reducing the overall difficulty of assembling the car seat.

[0051] The present disclosure also provides a car leather cover, comprising a leather cover body and a fixing buckle 10 according to any of the above embodiments, wherein the fixing buckle 10 is connected to the leather cover body. Furthermore, the fixing buckle 10 is connected to the side of the leather cover body that faces away from the outside, i.e., the fixing buckle 10 is connected to the leather cover body on the side facing the car seat body.

[0052] The present disclosure also provides a car seat comprising a seat foam, a support rod, and the car cover of the aforementioned embodiment. The seat foam partially wraps around the support rod, and a portion of the support rod structure is positioned within a gap in the seat foam. The car cover is buckled to the portion of the support rod structure. Specifically, the car cover is buckled to the support rod via a fixed hook 10 of the present solution, thereby covering the seat foam with the car cover, thereby forming a car seat that is less susceptible to car cover displacement.

[0053] Compared with the prior art, the present disclosure has at least the following advantages:

[0054] The above-mentioned fixed hook 10 has a first buckle component 310 and a second buckle component 320, that is, a first buckle tooth 311, a second buckle tooth 321, a third buckle tooth 312 and a fourth buckle tooth 322. The first buckle tooth 311, the second buckle tooth 321, the third buckle tooth 312 and the fourth buckle tooth 322 are all inclined toward the bottom of the hook shell 200, thereby playing a role in guiding the support rod of the car seat to be buckled. Since the extension line of the first buckle tooth 311 and the third buckle tooth 312 forms a first preset angle, and the extension line of the second buckle tooth 321 and the fourth buckle tooth 322 forms a second preset angle, The preset angle enhances the connection strength between the fixed hook 10 and the support rod, making it less likely for the support rod to fall out after passing through the first horizontal gap and the second horizontal gap in sequence, and the support rod contacts the second buckle component 320 and the buckle shell 200 respectively. Even if the bottom surface of the seat is subjected to pressure from the human body, it is less likely for the car leather cover to shift due to loosening of the connection part. The setting of the first buckle component 310 and the second buckle component 320 can further enhance the connection strength between the fixed hook 10 and the support rod, making it less likely for the support rod to fall out of the buckle shell 200.

[0055] The above-described embodiments merely represent several implementation methods of the present disclosure. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the scope of the present disclosure, all of which fall within the scope of protection of the present disclosure. Therefore, the scope of protection of the disclosed patent shall be determined by the appended claims.
